Audio File Info Viewer

See codec, bitrate, sample rate, channels, duration and ID3 tags for any audio file. No conversion.

About this audio info viewer

Drop in any audio file and get a clean readout of what's actually in it: container format, codec, bitrate, sample rate, channels, duration and ID3 tags. We don't analyse or index your file, and nothing is converted.

Useful for sanity-checking a download ("is this really 320 kbps?"), inspecting recordings before you upload them somewhere, or just understanding why a file behaves the way it does in your DAW or media player.

How to inspect an audio file

  1. 01

    Drop in a file

    MP3, WAV, FLAC, OGG, M4A, AAC, OPUS, AIFF and more.

  2. 02

    Read the report

    Codec, bitrate, sample rate, channels, duration and any embedded tags.

  3. 03

    Decide what to do

    Use the report to pick a converter, compressor or trimmer next.

Why use this audio info tool

  • Codec, bitrate, sample rate, channels and bit depth
  • Duration and total size
  • Container format and stream count
  • Embedded ID3 tags (title, artist, album, year, genre)
  • Free and private — we don't analyse or index your file
  • No conversion is performed — the file is unchanged

Audio info FAQ

Is my file kept private?

Yes. We don't analyse or index your file — the output is just text printed back to the page.

Why does my MP3 say 'CBR' or 'VBR'?

Constant or Variable Bit Rate. CBR keeps the same bitrate the whole way through; VBR varies it depending on complexity to save space. Both are valid MP3 modes.

What if my file is corrupt?

The tool will still try and the report will include any errors it found while parsing. That's often enough to know what's wrong.

Will it read embedded album art?

It reports whether art is present and what format it's in, but it doesn't display the image here — for that, use the ID3 editor.
